' CARD INDEX AND FILE I Filed A 18. 31. 1927 gwwwkoe Patented Nov. 12,1929 MALCOLM MCDONALD, ORENCO, OREGON CARD rnnnxnnn nrnn Applicationfiled August 31, 1927. seriai No. 216,616.

This application relates to my application in the United States PatentOflice, filed April 15 1926, Patent No. 1,649,244, Nov. 15, 1927, upon aCard index and file, and my present application relates to twoapplications for patent filed concurrently herewith, upon a Card indexand file, Ser. Nos. 216,214 and 216,615. g

The primary object of my present invention 10 is to provide simple andefficient means for the maintaining of card indexes and the like.

A further object of my invention consists in providing a supporting yokefor the card holder disposed independent of the yoke to be receivedwithin the guideway of the tray and gives a greaterfreedom of movementand a maximum of spaced relationship for inspection between the card andthe adjacent card placed thereby.

With these and incidental objects in view, the invention. consists incertain novel features of construction and combination of parts, theessential elements of which are set forth in the appended claims, and apreferred form of embodiment of which is hereinafter shown withreference to the drawings which accompany and form a part of thisspecification.

In the drawings:

. Fig. 1 is a fragmentary top plan View of the tray with the cardssupported therein.

Fig. 2 is a fragmentary cross-sectional view,

taken on line 2-2 of Fig.1, looking in the y direction indicated.

Fig. 3 is a fragmentary top plan view of the card holder and yokes andof the tray with which the same are associated.

Like reference characters refer to like parts throughout the severalviews.

1 is the card tray having guideway 18 disposed lengthwise thereof. In apreferred form of embodiment of the invention the yoke is shown at 17 inFig. 2, and is formed about a central guideway 18, and has oppositelydisposed upturned bosses 19 and 20 through which the ends 21 and 22 ofthe card holder 23 may be made to pass. A central notch 15 is providedin the card holder 23 with which the indicator mark 16 in each card ismade 50 to register to insure the positioning of the 22 of the cardholder-23 'therethrouglr and I cards in uniform spacing and alignment. Ac The yoke 17 should be made of material havfreedom should be providedin the'bos ses'19 and'20 to permit of a free turning of the card holder23 within the openings disposed i said bosses. I

In the construction of the bosses of the yokes, as illustrated in Fig.3, the boss is formed by the upturning of flanges 24 and 25 to form anengaging socket, into which the card holder is made to engage. This formof construction may be used and the. yoke made of sheet stock, withoutthe swaging or upsetting of the ends, and the central portion 26 shouldbe so made as to permit of a snap engagement with the centralguidewaylS, thus permitting the removal of a yoke with its card from theindex or the insertion of the same after a card has been placed therein.

. While the form of mechanism herein shown and described is admirablyadaptedto fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the 1 invention to the one form ofembodiment herein shown and described, as it is susceptible ofembodiment in various forms, all com ing within the scope of the claimswhich follow:

What I claimis; 1 1. In a device of the class described, a' card indextray, a central guideway disposed longitudinally of the card index tray,said guideway being disposed upon the upper surface of the bottom of thecard tray and being rounded in form, a series of slidable yoke elementsassociated with the guideway and adapted to engagement and disengagementtherefrom by being pressed into place relative to the guideway, the yokeelements having upturned bosses ateach end and journal bearings disposedtherein, and a card holder journaled associated with the guideway andadapted to asnap engagement and disengagement with the guideway,horizontal bearings disposed at either end of the yoke elements and acard holider journaled Within the bearings of each 0 6'. I y 3. In a,device of the class described, a card index tray, a guideway, rounded incross section assocated with the upper side of the bottom of the cardtray, a multiple of yokes adapted toa snap engagement and disengagementwith the guideway associated therewith, a series of horizontal bearingsassociated with either end of the yoke andformed bynpturning ears formedof the yoke stock, and card holders having notches formed centrally oftheir edges journaled vWithin them-bearings of he Y kes, and. ,a cardhav ng an ind c tor mark formed central the lower side of its nd p ac bew n he opp sitely disposed su fa of th Car h der.
